Definitions
- This invention is related with the application of geminals zwitterionics liquids as wettability modifiers of rocks such as limestone, dolomite, sandstone, quartz or heterogeneous lithologies in the presence of brines with high content of divalent ions such as calcium, magnesium, barium and strontium, high temperature and high pressure in enhanced oil recovery process to increase oil recovery factor.
- geminals zwitterionics liquids as wettability modifiers of rocks such as limestone, dolomite, sandstone, quartz or heterogeneous lithologies in the presence of brines with high content of divalent ions such as calcium, magnesium, barium and strontium, high temperature and high pressure in enhanced oil recovery process to increase oil recovery factor.
- Zwitterionics liquids are compounds that containing the cation and anion at different atoms of the same molecule, making them electrically neutral and gives them the opportunity to behave as acids or bases (donor or acceptor) depending on the characteristics of the medium which means they are intelligent molecules can be designed to work efficiently depending on the characteristics of one or more specific environmental.
- Geminals zwitterionics liquids (2) are a family that is characterized by having two hydrocarbon chains (A), a molecular bridge (B), and two zwitterionic polar groups (C). .
- Wettability modifier is defined as a surfactant capable of changing the affinity of reservoir rock in favorably manner.
- the wettability is a measure of the interaction between the phases present in the reservoir and is a function of interfacial chemistry of these phases and determines the tendency of a fluid for moving or adhering to a solid surface in the presence of other immiscible fluids.
- the wettability of a rock can be naturally modified by adsorption of polar compounds, the formation of deposits of organic material that was originally in the oil or by external agents. Changes in the wettability affect capillary pressure, relative permeability, residual oil saturation and irreducible water saturation. Additionally and equally important is the recognition that the confinement of the fluid substantially modifies the behavior of their phases with respect to its properties in the bulk.
- U.S. Patent 4,509,951 (Enhanced recovery by imbibition process) protects an enhanced recovery process that involves the injecting in the reservoir of a wettability modifier that consisting of a mixture of different types of products, within which are ammonium salts, hydroxides of alkalis metals, alkyl tripolyphosphates and carbonates and bicarbonates of alkali metals.
- U.S. Patent Application 2009/0023618 A1 (Method of Oil Recovery) protects an enhanced recovery process that involves the injecting to the reservoir of a wettability modifier consisting of a mixture of different types of organophosphorus compounds.
